Description

Children's tooth appliance Technical Field The utility model relates to the field of medical appliances, in particular to a children tooth appliance. Background The dental appliance is a common dental appliance, and has regular shape, and is sleeved on the teeth of a user and continuously applies force to the teeth of the user so as to achieve the purpose of correcting the teeth of the user. The traditional orthodontic treatment is to bond a bracket on a tooth surface, ligate an arch wire in a groove of the bracket, generate correction force by utilizing elastic deformation of the arch wire, transmit the correction force to teeth through the bracket, so as to realize movement of the teeth, generally, the tail end of the arch wire adopts a back bending mode to prevent the arch wire from stimulating the oral cavity, for example, a bracket forceps disclosed in Chinese patent publication No. CN221534115U is specially used for the back bending of the tail end of the arch wire, but the elasticity of the arch wire and the contact of muscle peristalsis in the oral cavity are realized, the arch wire can be gradually stretched over time, the back bending arch wire is straightened, and the tail end tip stimulates the oral cavity, especially for children, the crowd needing to carry out a large amount of communication and communication is more easy to straighten the tail end of the arch wire in treatment, so that oral cavity discomfort is caused, and therefore, a new scheme is required to be provided to solve the problems. Disclosure of Invention The utility model overcomes the defects of the prior art and provides the children tooth appliance.
